[0075] Working process of the present invention:
[0076] refer to figure 1 , image 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , during work, the 220V power supply enters the power module 12 through the power socket 11, and the power module 12 converts the 220V voltage into three circuits, one for the first fan 51, the second fan 52, the third fan 53 and the fourth fan of the fan part 5. 54 supplies power; one way supplies power to the UHP controller 46;
[0077] Main board 21 is connected video signal through HMDI video interface, and main board 21 is sent to daughter board 33 after the video signal is processed, and the surface micromirror of DMD chip 36 on daughter board carries out corresponding flipping according to the processed video signal; Meanwhile, main board 21 The UHP controller 46 is controlled to turn on the UHP lamp 41. The light emitted by the UHP lamp 41 passes through the color wheel 47, the optical path conversion module 44, and e...

The invention discloses a DLP projection technology application development platform, which comprises a power supply part, a main control board, a daughter board part, a lamplight part, a fan part, arotary swinging platform, a lens, a camera and a case shell, wherein all the components are reasonably configured and highly integrated into a whole through the design of the case shell, and the daughter board part, the lamplight part, the fan part and the camera are controlled through the main control board, so that the projection platform is fully developed. Development flexibility is provided to the maximum extent; the architecture design of the main control board and the daughter board is adopted, so that the platform is compatible with various DMD projection chips at the lowest cost; theprojection platform structure provided with the rotary swinging platform meets the requirements of multi-angle projection and fine angle adjustment; multi-directional fan arrangement is beneficial toheat dissipation; the main control board is arranged on a board card support so that external connection of multiple interfaces is facilitated; the system has the advantages of reasonable structure,high integration level, high degree of freedom of work, convenient debugging, good projection effect, good compatibility and strong interaction capability.
Description
technical field [0001] The invention relates to the field of projection technology, in particular to a DLP projection technology application development platform. Background technique [0002] As the application of projection platforms in home use, education conferences, mainstream engineering, surveying, professional theaters and other scenarios has become more and more popular, users' requirements for projection platforms have gradually changed from single projection to intelligent and interactive applications. [0003] Traditional projectors usually place the mainboard inside the chassis, but for small and medium-sized projection platform developers, it often costs a lot to redesign the mainboard, configuration interface, internal component layout, etc. in order to realize different intelligent functions; at the same time, due to chip packaging , pins, etc., traditional projectors are often only compatible with one kind of projection chip, which brings disadvantages such ...
